Oh, hell. I wrote this before I finished my first cup of coffee this
morning. It really wasn't meant as code to use so much as a guideline
for accomplishing what you need.

Instead of "\<a>\" it should read "</a>". I need stronger coffee or a
caffeine IV. ;-)

Anyway, the part displaying the lines should display all lines and
only replace those which match the word. That part should be more
like this:

foreach ($lines as $line_num=>$line) {
if (in_arrary ($line_num, $match)) {
echo "a href=\"#$line_num\">$line</a>";
} else {
echo $line;
}
}
